The browser sees fake links as a scam. For example, if you have a hyperlink that has "http://some-title.com" at its title, but it instead redirects to "http://some-title.com/othertitle", the web browser of the recipient can think that the link is an attempt to SCAM. To avoid this, make sure that the title isn't misleading.
Title: some-title.com, link: http://www.some-title.com
Title: some-title.com/campaign, link: http://www.some-title.com/campaign
